PORTABLE VENTILATING OUTFIT.

Application 1ed September 23, 192?. Serial No. 590,194.

To all whom it may concern.'

Be it known that we, GEORGE C...BREIDERT and VERNE E. STARxs, citizens of the United States, residing, respectively, at Chicago, in

the county of Cook and State of Illinois, and Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Portable Ventilating Outfits, of which the following is a specification. l

This invention relates to Ventilating apparatus, and has for its main object toprovide a simple, inexpensive and efficient portable. Ventilating appliance which can readily be applied to the windows of residences and other buildings to draw E foul air from the interior orinduce fresh the aoeompanying'drawing in which we have air from the outside, without involving any alteration or defacement of the window structure.

Another object of the invention is to provide an appliance of the character specified that shall be capable of adjustment to t varying heightsr of window frame heads, and varying widthsof 'window openings.

A further object is to provide` a unitary Ventilating structure for application to windows wherein an electrically driven fan, a switch, a plug socket, circuit lines, suspension means .and the bottom closure member mayall `be mountedon a panel adapted to fit the upper portion of a. window frame. Other objects and attendant advantages of the invention will be understood by persons skilled in the art from the following detailed "description, taken in connection with illustrated one practical and approved embodiment lof lour invention in association with two means or instrumentalities for suspending the same from vthe head of the window frame and wherein.-

Fig.- 1 is a front elevation showing oui` portable ventilator applied to a window;

Fig. 2 is an edge elevation partly in vertical transverse section;

' Fig. 3 is a fragmentary detail view illustrating a suspending `device applicable to inset window frameC heads;

Fig. 4: is a perspective elevation of one of` the suspension hooks;

Fig. 5 isa front elevation of a modified form of portable ventilator that is adjustable widthwise to fit varying widths of window openings; Fig. 6 is a view similar to Fig. 2, showing the ventilatorl of Fig. 5 applied to a window frame; v

Fig. 7 is a top plan view of the frame shown in Fig. 5, partially brokenv away in section;

Fig. 8 is a front elevation of a lengthwise adjustable closure strip adapted to be se-' cured to the top bar-of the upper sash; and o Fig. 9 is an end elevation of Fig. 8.

Referring to the drawings, 5 designates as an entirety an ordinary box window frame, and 6 the head thereof. 7 and 8 designate the usual upper and lower counterweighted sliding sash.

In the embodiment of the invention vshown in Figs. 1 `to 4 inclusive, 9 designates a. fiat panel of rectangular form and of slightly greater width than the window frame opening and designed to overhang the upperportion of the lat-ter, said panel having a een? tral circular opening 10, around which is secured a ring 11 carrying radial arms 12 in turn carrying a ring 13 which constitu-tes a holder and support for an electric motor 14, the armature shaft of which is equipped with a fan 15. .The panel 9 is preferably made of sheet metal, and provided with marginal'ribs or anges 9a to stiien the same.

On one corner of the panel (the lower right 'hand corner as herein shown) is mounted a switch 16; and on another corner (the upper right. hand corner as herein shown) is mounted an ordinary plug socket 17. Circuit lines 18 from'the plug socket- 17 to the motor may be covered by suitable housing strips 19. Y

On the upper end of the panel are a pair of brackets 20 carrying set screws 21 that extend through slots 22 in the lower shank portions of a pair of hooks 23.- As shown in Fig. 4 the free ends vof the hooks 23 are preferably forked and pointed as shown at width to span the space between the lower edge of the panel and the top of the lowered upper sash 7, as clearly shown in Fig. 2.` bviously the hinging of the closure strip 25 enables it to co-operate with the sash 7 without requiring the latter to be lowered to an exact position; and when the Ventilator is not in use the upper sash may be raised without requiring the removal of the Ventilator, the closure strip 25 merely swinging upwardly out of the way,

In some building structures the frame' head is inset or flush with the plaster wall, as shown at 6 in Fig. 3. To co-operate with such a structure, in lieu of the suspension .hook 23 a hinge 26 may be secured to the head 6, its depending leaf being slotted to receive the set screw 2l mounted in the bracket 20. ln this structure the ventilator is applied and removed by simply applying and removing the set screws 21.

rlhe structure hereinabove described employs a single panel of fixed dimensions and, of course, adaptable only to a window frame opening of the same or a somewhat less width. ln Figs. 5 toY 9 inclusive we have shown another form of the invention employing a pair of relatively slidable panel sections, which adapt the device to windows of considerable Varying widths. In' these views, 27 designates a vertically disposed sheet metal strip provided on its upper and lower edges with oppositely facing slideways or guides 28 and 29 respectively,-which are considerably extended on one side of the strip 27, as shown at 28 and 29. Slidably mounted at their upper and lower edges in these guide strips are a pair of panel sections 30 and 31 which. lie in a common Vertical plane and, in the narrowest adjustment' of the panel, meet edge to edge in a jointindicated at 32, which joint, in the contiguous position of the panel sections, may be covered by a lap strip 33 attached to one of the sections and overlapping the adjacent edge of the other. The fan, its plug, switch and circuit wires are mounted on one of the panel sections, preferably the larger'sectio'n 30, substantially in the manner shown in F ig. l; and the suspension hooks 23 are attached to the outer ends of the two panels, respectively, in the manner and by vmeans previously described. This construction enables the panel to' be widened from the narrowest width shown in Fig. 5 to an extent substantially equal to the width of the mounting strip 27.

rThe closure strip, instead of being hinged ,to the lower edge of the panel, .as in the constructions shown in Figs. 1 to 41 inclusive, is attached to the top bar of the upper sash. The strip is lengthwise adjustable, and comprises a pair of slidably interitted horizontal strips 34 and 35 havlng 0n rtheir rear ledges interitting Vertical flanges '34 and 35', respectively. rlhe strips 34 and 35 are attached 'at their ends to the window sash by screws 36. The closure strip is first adjusted lengthwise to the width o1,v the4 particular window sash, and is then attached to the latter by the means described, and when 'the panel is 'applied to the window, the upper sash is lowered until the free edge of the closure strip substantially registers with the lower edge of the panel.

From the foregoing it will be seen that the appliance of our present `invention obviates the necessity of making permanent installations of Ventilating fans on'windows, which is a great advantage, especially in residences and the like where it may be desired to use the ventilator only occasionally or at special times. Its readily portable character enables it to be applied and connected upto a current circuit line with a minimum of time and trouble, and as easily and quickly removed.

Manifestly the specificv details of structure and relative arrangement herein shown and described may be variously changed without involving any departure from the substance of the invention or sacrificing any advantage or utility thereof. Hence, we reserve such modifications as :tall within the spirit and purview of the appended claims.
